Review: Devo ancora provarlo - Speriamo che funzioni come previsto grazie
Review: Loving this so far! - Having looked at loads of these tumblers and been shocked at the prices charged, this one seems to be a bargain. Very well made and comes with everything needed to get started. Good sized strong drum and sturdy, professional feel base. Useful timer and speed controls. The drum on mine came with the additional metal end (not shown in picture) which does make it run ourt of true on the rollers as others have mentioned, but it pulls off easily and seems better for not having it on there.

A: I don’t think there is a warranty for it. However, if it’s defective call the company. They seem to be really good at doing the right thing

**Q: Can you confirm the voltage rating of the power cord? only 110v or up to 240v? thank you.**
A: The power supply will work with 100-240v. It has a US plug.

**Q: I get an error code everytime I try and run it doesn't anyone know why? I hardly have anything in it.**

### ⭐⭐⭐⭐⭐ Trying things differently and getting awesome results
*by K***S on 26 November 2025*

So far so good, but customer service is lacking so keep that in mind. I emailed weeks ago and never got a response to a question. When the tumbler shuts off it is still on day 1, so I wasn't sure if it was supposed to be that way. I thought it had stalled, so I ran it another day. Later on, I ran a second load of agates in it, and it did the same thing, so I can only assume it is supposed to do that. I've only ran it twice, but I'm loving the results. I didn't use the grit they provided. I use polly grit, and I'm getting awesome results. I will use their grit one day to see what it does. I do lapidary work, so I was doing things different. Either grit you use, I recommend going to step 3, just like other reviews said. Here's something to try. Use grit 3 fine pre polish, a tablespoon, along with half a tablespoon of #1 coarse. Run it for 3 Days on speed 3. Then run it with the same contents for another day on speed 1. Rinse everything. Reload and add in grit 4, tablespoon, with half a tablespoon of cerium oxide. Run the grit 4 and cerium for 2 days on speed 1. I had very good shine and rounded edges. But keep in mind, this process is for agates. For softer stones, you'll want to slow your speed and maybe drop a day. If this thing keeps working, or at least a good while, I would definitely invest in it again. My only regret is that I didn't buy their larger tumbler.
